Cole is interested in the connections between above-ground and below-ground processes and how they shape plant communities, plant productivity, soil ecology, and overall soil health. He is particularly focused on the intersection of agriculture and ecology, with an emphasis on microbial ecology and plant ecophysiology, especially in how resources flow through ecosystems. By deepening his understanding of soil health and management practices that enhance soil fertility, Cole aims to positively impact ecosystem health, agricultural producers and the broader community.
Cole’s work has consistently focused on restoring degraded landscapes, with an emphasis on building resilient ecosystems and linking ecosystem health to community well-being. He has had the opportunity to work in environments heavily impacted by pollution and ecological degradation, including overgrazed rangelands dominated by invasive species in the great basin, large-scale urban construction sites contaminated with hydrocarbons and heavy metals, and eastern hardwood forests polluted by radioactive isotopes from nuclear materials production. These experiences have deepened his understanding of below-ground processes and fostered a deep appreciation for soil ecosystems. This background has shaped his bottom-up approach to ecological restoration, which he applies across diverse systems and contexts.
